Not really. More and more NASA is acknowledging that the aging shuttle fleet is risky to keep flying.
Considering the fact that pieces seem to fall off the shuttle and do some damage every time it’s launched, I can sort of understand some of the thinking behind this.
Several of the last few missions have required external inspection of the shuttle, while in orbit, to determine if reentry can be accomplished without burning up. Heat shield damage from falling fuel tank foam is the danger.
It’s ironic to note that fuel tank foam coming apart on launch was never a problem until NASA was forced to “go green” and replace the original foam with a more environmentally “friendly” foam.
It’s not like the amount of “ozone depleting” foam used on the shuttle was going to make much difference in the big picture.
